I want to create a subsubparagraph heading (in order to comply with phd guidlines for formatting). I've copied code from article.cls and just made everything 'lower'. However, when I do, although the subsubparagraph exists, it prints the title twice.

MWE

\documentclass{article}
\makeatletter
\newcounter{subsubparagraph}[subparagraph]
\renewcommand\thesubsubparagraph{\thesubparagraph.\@arabic\c@subsubparagraph}
\newcommand\subsubparagraph{\@startsection{subsubparagraph}{6}{\parindent}%
                                       {3.25ex \@plus1ex \@minus .2ex}%
                                       {-1em}%
                              {\normalfont\normalsize\bfseries}}
\newcommand*\l@subsubparagraph{\@dottedtocline{6}{10em}{5em}}
\makeatother

\begin{document}
\paragraph{Foo}
\subparagraph{Bar}
\subsubparagraph{Foo bar!!!}

\end{document}

seeing double when defining subsubparagraph

The subsubparagraph needs to have all the properties of subparagraph, with possible additional indentation (which currently I've omitted to keep the new code as close to that found in article.cls)

  • Add \newcommand{\subsubparagraphmark}[1]{}. I don't see why an additional sectional unit is needed, as already five below \chapter are provided. – egreg Jan 18 '13 at 16:47

There is no need to load new packages.

In order to define a new sectional unit "foo" you need:

  1. the command \foo, usually defined in terms of \@startsection
  2. a counter, usually with the same name, foo
  3. a command for setting the entry in the table of contents, \l@foo
  4. a command for possibly setting the mark, \foomark

So the complete definition would be

\makeatletter
\newcounter{subsubparagraph}[subparagraph]
\renewcommand\thesubsubparagraph{%
  \thesubparagraph.\@arabic\c@subsubparagraph}
\newcommand\subsubparagraph{%
  \@startsection{subsubparagraph}    % counter
    {6}                              % level
    {\parindent}                     % indent
    {3.25ex \@plus 1ex \@minus .2ex} % beforeskip
    {-1em}                           % afterskip
    {\normalfont\normalsize\bfseries}}
\newcommand\l@subsubparagraph{\@dottedtocline{6}{10em}{5em}}
\newcommand{\subsubparagraphmark}[1]{}
\makeatother

Using the titlesec package:

\documentclass{article}

\usepackage{titlesec}
\titleclass{\subsubparagraph}{straight}[\subparagraph]
\newcounter{subsubparagraph}
\renewcommand{\thesubsubparagraph}{\Alph{subsubparagraph}}
\titleformat{\subsubparagraph}[runin]{\normalfont\normalsize\bfseries}{\thesubsubparagraph}{1em}{}
\titlespacing*{\subsubparagraph} {\parindent}{3.25ex plus 1ex minus .2ex}{1em}

\begin{document}
\paragraph{Foo}
\subparagraph{Bar}
\subsubparagraph{Foo bar!!!}

\end{document}

If for some reason you add \setcounter{tocdepth}{6} to get subsubparagraph to appear in the table of contents and include the hyperref package, you will need to include 

\makeatletter
\def\toclevel@subsubparagraph{6}
\makeatother

In order for the pdf index to be made properly.
